Standard Sieve, as the name implies, must conform to the Standard Sieve tool. Standard Sieve is a tool for particle size classification and particle size detection of material particles. It is a sieve that is inspected, identified, and deemed to be in compliance with the agreement by a designated agency. This is an important sign that it is different from general sieves. The test sieve has strict mesh size regulations. The test sieve uses the mesh size to represent the specifications of each sieve. The sieve number is equivalent to "mesh" but not equal to "mesh".

A set of Standard Sieve tools for particle size analysis of material particle size composition is composed of a set of sieves with standardized sieve size, also known as standard set of sieves.

Standard Sieve is a sieve standardized by law. There are two kinds of mesh screen and plate screen. Usually made of brass, phosphor bronze or stainless steel. The mesh of the mesh screen is woven by metal wires in a square, and is divided into several specifications according to the opening of the screen holes or the diameter of the wires. The screen frame is cylindrical, and screens of the same diameter can be used in combination. It is used to determine the particle size distribution of powder materials and granular materials.

Standard Sieve A set of Standard Sieve tools used to measure the particle size composition of materials. It is the main tool for screening analysis. It is composed of a set of several layers of circular sieves with a diameter of 200mm manufactured according to the standard with a certain ratio of mesh size, mesh width and wire diameter. With a cover and a bottom, it can be operated manually or installed on a sieve machine for sieving. Its layers are arranged according to the sieve holes from large to small and from top to bottom. It is mainly used to determine the composition of materials with a particle size below 6mm. The layer order of each sieve is called the sieve sequence, the ratio of the sieve size of two adjacent sieves is called the sieve ratio, and the sieve used as the benchmark is called the base sieve. As long as the two parameters of sieve ratio and base sieve are known, the sieve size of each sieve of this series of standard sieves can be calculated. According to the sieve ratio and base sieve mesh size, it is divided into various Standard Sieve systems.
